Rule 21-1503 - NOTICES

1503.1

To collect information consistent with the purposes of the Act and this chapter, WASA may require any party who discharges, or whom WASA reasonably believes discharges, into the District's wastewater system, to provide reports concerning the nature, contents, quantity and frequency of such discharges and the party's actions, if any, to monitor or alter such discharges. WASA may require such reports regardless of whether the party shall have a permit under the Act.

1503.2

WASA may issue a discharge notification letter to such parties, identifying what specific information is sought, the frequency with which the information shall be provided, and a statement concerning the period of time during which the obligation to provide such information will continue.

1503.3

All Industrial Users shall promptly notify WASA prior to any new or increased contribution of pollutants or change in the nature of pollutants or substantial change in the volume or character of pollutants in their discharge, including the listed and characteristic hazardous waste for which the Industrial User has submitted initial notification under § 1503.6. WASA reserves the right to prohibit or impose conditions on the discharge of any new, increased or changed contribution of pollutants.

1503.4

All Industrial Users that experience an unplanned discharge due to a spill, slug discharge, or other potential problem, shall notify WASA as follows:

(a) All Industrial Users shall notify WASA immediately of all discharges that could cause problems to the District's wastewater system, including any slug loadings, which are defined as pollutant discharges which violate the specific prohibitions under § 1501.4;

(b) The notification shall include the date, time, and location of the discharge; type, concentration and volume of waste; and corrective actions. The Industrial User shall be liable for any expense, loss, or damage to the District's wastewater system, in addition to any fines that WASA imposes;

(c) Within five (5) days following the unplanned discharge, the Industrial User shall submit to WASA a detailed written report describing the cause of the discharge and the measures to be taken by the Industrial User to prevent similar occurrences in the future; and

(d) If the unplanned discharge contains a listed or characteristic hazardous waste, as defined in 40 C.F.R. Part 261 and District regulations, the Industrial User shall also comply with the requirements of § 1503.6(a).

1503.5

Notice of Changed Discharge - All Significant Industrial Users are required to notify WASA immediately of any changes at their facility affecting the potential for a slug discharge.

1503.6

All Industrial Users proposing to discharge hazardous waste into the District's wastewater system shall comply with the following requirements:

(a) Industrial Users shall make a written notification to WASA, the Mayor, and the director of EPA's Region III Waste Management Division, prior to a discharge into the District's wastewater system of a substance which, if otherwise disposed of, would be a hazardous waste under 40 C.F.R. Part 261 and District regulations. Such notification shall include:

(1) The name of the hazardous waste as set forth in 40 C.F.R. Part 261;

(2) EPA hazardous waste number;

(3) The type of discharge (continuous, batch, or other); and

(4) A statement certifying that the Industrial User has a program in place to reduce the volume and toxicity of hazardous wastes generated to the degree it has determined to be economically practical;

(b) If the Industrial User intends to discharge more than one hundred kilograms (100 kg) of hazardous waste per calendar month to the District's wastewater system, the notification shall also contain the following information to the extent the information is known and readily available to the Industrial User:

(1) An identification of the hazardous constituents contained in the wastes;

(2) An estimation of the mass and concentration of such constituents in the wastestream to be discharged during the calendar month; and

(3) An estimation of the mass of constituents in the wastestream expected to be discharged during the following twelve (12) months;

(c) Industrial Users shall provide notification prior to the discharge of a listed or characteristic hazardous waste. This notification shall be submitted only once for each hazardous waste intended to be discharged. However, notifications of changed discharges shall be submitted under 40 C.F.R. § 403.12(j) and § 1503.5. The notification requirement, however, does not apply to pollutants already reported under the self-monitoring requirements of 40 C.F.R. § 403.12(b), (d), and (e) and § 1508; and

(d) WASA shall review the hazardous waste discharge notification and may issue a new or revised pretreatment permit. Industrial Users shall not discharge a listed or characteristic hazardous waste prior to the issuance of a pretreatment permit that authorizes the discharge.

1503.7

In the case of any new regulations under § 3001 of the Resource Conservation and Recovery Act (RCRA) identifying additional characteristics of hazardous waste or listing any additional substance as a hazardous waste, the Industrial User shall notify WASA, the EPA Regional Waste Management Waste Division Director, and the District of Columbia hazardous waste authorities of the discharge of such substance within ninety (90) days of the effective date of such regulations.
